Projector fan faulty?

[ScoobyDoo]

Purchased a Benq w1210st projector last month for gaming and love the picture quality etc.
I've now noticed that after the projector has been on for about 20mins one of the fans is making a high pitched whistle.
If I blow on the fan it stops for a couple of mins and then starts again.
It also stops for a while if I move or tap the projector

Does this sound like a faulty fan? If so it's going to have to go back to Benq for repair and I'll be without it for a couple of weeks

It is a new one but I think the policy is after 30 days then it's a warranty repair. I'll see how it goes over the Xmas period, hopefully it may settle down. If not I'll contact the company I purchased it off to see what they say.

I'll call up in the new year and get it repaired. I've checked and the fan is working and blowing the hot air out, it just makes a funny noise after about 20 mins although I used it for over 30 mins last night and it didn't make a sound!
